Gary Anderson roared into the last eight of the PDC World Championship and then took aim at commentator Wayne Mardle. The Scot, who was fuming at Mensur Suljovic’s slow pace, said: 'Now Wayne’s telling everyone if you’ve got a problem with a player slow him down, or do what you can to put him off. What a numpty! That’s great for television, and great to tell kids what to do, isn’t it? Proud of you Wayne.'
